This makes sure that closed handle scopes are properly zapped even if an
enclosing NoHandleAllocation shrunk the limit. It also unifies the code
that performs scope closing for internal and external handle scopes.

This gets rid of more places where Persistent handles are copied
(see crbug.com/236290 ).

Transition plan: after this CL, Blink will be modified to work both with and
without the #define, then the #define will be removed from V8.

The corresponding Blink side changes are in https://codereview.chromium.org/15670010/ .

Now that the only known client console.profiles was removed from Blink:
https://src.chromium.org/viewvc/blink?revision=151136&view=revision
https://src.chromium.org/viewvc/blink?revision=151196&view=revision
this method can be deprecated and all the code that supports filtering
CPU profiles based on security origins can be later removed.

Drive-by fix: in line with CpuProfiler changes deprecated HeapProfiler::FindHeapSnapshot to reduce v8 API surface. FindHeapSnapshot may well be implemented based on existing GetSnapshotCount/GetSnapshot and it is only used in the tests.
